The bge Gigabit Ethernet driver is a multi-threaded, load-
able, clonable, GLD-based STREAMS driver supporting the Data
Link Provider Interface, dlpi(7P), on Broadcom BCM57xx
(BCM5700/5701/5703/5704/5705/5705M/5714/5721/5751/5751M/5782/5788
on x86) Gigabit Ethernet controllers fitted to the system
motherboard. With the exception of BCM5700/BCM5701/BCM5704S,
these devices incorporate both MAC and PHY functions and
provide three-speed (copper) Ethernet operation on the RJ-45
connectors. (BCM5700/BCM5701/BCM5704S do not have a PHY
integrated into the MAC chipset.)
